FRIGIDAIRE CORPORATION, A CORPORATION OF DELAWARE REFRIGERATINGAPPARATUS Application filed November 80, 1925, Serial No. 72,096.Renewed December 18, 1928.

The present invention invention relates to refrigerators andparticularly to refrigerators in which the cabinet thereof is dividedinto aplurality of compartments.

In certain types of mechanical refrigerator, water is frozen inreceptacles and the ice blocks are removed from the receptacles anddelivered to an ice storage chamber. One of the objects of the presentinvention is to simm plify this type of refrigerator. One manner ofcarrying out this object is to form a portion of a partition wall, whichdivides the refrigerator cabinet into afood compartment and a coolingcompartment into a chamber for storing blocks of ice which have beenfrozen within the cooling chamber.

Another manner of carrying out the above object is to arrange the icestorage chamber in such a position with respect to the other portions ofthe partition wall that a plurality of air passages, connecting thecompartments, can be arranged at different levels with respect to oneanother whereby natural circulation of air will take place.

Other and further objects of the present invention will be apparent fromthe following description reference being had to the accompanyingdrawings wherein a preferred form of embodiment of the present inventionis clearly shown.

In the drawings:

Fig. 1 is a sectional view of the cabinet of the improved refrigeratorshowing a refrigerating machine in elevation.

Fig. 2 is a fragmentary sectional view taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on line 3-3 of Fig. 1, and

Fig. 4 is a front view in elevation showing a door of the cabinet open.

Referring to the drawing, the refrigerator includes a cabinet having amachine compartment 21, a cooling compartment 22 and a food compartment23. The cooling com- .partment 22 and food compartment 23 are surroundedby insulation 25, the top portion 25 of the insulation being removableto provide access to the interior of the cooling compar tment 22. Thecooling compartment 22 is provided with a lining 26 which forms theback, front and opposite side walls for said compartment. The lowerportion of lining 26 extends inwardly to provide a flange 27. Thecompartment 23 is provided with a lining 29 which forms the bottom,back, front and opposite side walls for said compartment. The upperportion of lining 29 extends inwardly to substantially the same distanceas the flange 27 of lining 26 to provide a flange 30. I

A partition wall 32 between compartments 22 and 23 is secured to theflanges 27 and 30 by bolts 33 which bolts are also utilized for securingflange 27 to flange 30, there being a gasket 34 interposed between theseflanges. The partition wall 32 includes a downward. ly extending portionproviding a chamber 36 which chamber includes a back wall 37. and afront wall 38, a bottom wall 39, a side wall 40 and an opposite sidewall 41.

- The refrigerating machine herein shown is substantially the same asthat shown and described in the patent to D. F. Keith, 1,510,147

of September 30. 1924, and shown in copending application Serial No.3789, filed January 21, 1925. For the purpose of this invention it isdeemed suflicient to state that this refrigerating machine is of theabsorption type'including a generator-absorber 43 which i adapted to beintermittently heated 30 and intermittently cooled for intermittentlyforcing refrigerant therefrom into an evaporator 44 and for withdrawingrefrigerant from the evaporator. As is disclosed in the aforementionedpatent and application, the 35 entire refrigerating machine is pivotallymounted and the evaporator 44 is adapted to 'rock from the positionshown in full line to the position shown in dotted line. The rockingfrom the full line position to the dotted line position is caused by thepresence of substantially all of the refrigerant in thegenerator-absorber 43, and, the evaporator is rocked from the dottedline position to the full line position when substantially all of therefrigerant is in the evaporator 44.

Water receptacles 46 are provided in the cooling compartment 22 forreceiving water which is delivered to the receptacles 46 in any suitablemanner as disclosed in the previously mentioned patent and application.Ice pegs 47 attached to the evaporator 44 extend within the waterreceptacles 46. During the cooling phase of the evaporator 44, heat willbe conducted from the water within the receptacles 46 to the evaporator44 through the pegs 47, in order to freeze the water into ice blocks.After a predetermined period of the refrigerating cycle, the evaporatorwill move from the position shown in the full line to that shown in thedot and dash line and since the pegs 47 are located at an angle, the iceblocks 49 will be withdrawn from the receptacles 46. When the coolingcompartment 22 becomes warmer the ice blocks 49 will slide from the pegs47 and will fall into an ice tray 50 located within the storage chamber36.

The front wall 38 of the storage chamber 36 is provided with an opening51 through which the ice tray 50 may be removed. The ice tray has ahandle 50 and a plate 50 which latter closes the opening 51 when the icetray is in position in the storage chamber. The front wall 53 of thecabinet 20 is provided with a door opening 54 providing access to thefood compartment 23. This door opening 54 is closed by door 55. Thestorage chamber 36 extends to such a distance within the foodcompartment 23 that the opening 51 of said chamber is in alignment withthe door opening 54 whereby the ice trays 50 can be removed through saiddoor opening. By constructing and arranging the elements as previouslydescribed, the ice trays are accessible and only one door is necessaryto provide access to the food compartment and to the ice trays.Furthermore, the construction of the present refrigerator is relativelysimple in that the partition wall between the cooling compartment andthe food compartment is also utilized as a storage chamber for ice.

The inclined portion 41 of side wall 41 of chamber 36 is provided withan opening 56 and the artition wall 32 is provided with openings 57 and58 located at the front and rear of the cabinet and adjacent that sideof the compartments op osite from the opening 56 and chamber 36. incethe chamber 36 is located below the other portion of the partition wall32, the opening 56 is located at a lower level than the openings 57 and58. These openings being located at different levels, naturalcirculation of air will take place, the relatively cold air passing fromcompartment 22 into chamber 36 thence through opening 56 into thecompartment 23, and the relatively warm air passing from the compartment23 through openin s 57 and 58 and into the compartment 22. owever itwill be noted that the opening 56 is above the bottom of the ice chamberand to one side of the ice drawer. Consequently the ice drawer is out ofthe path of air currents circulating thru the openings 57 and 58 and 56.The ice therefore is in a pocket wherein the air is relatively quiet,this pocket being included between the portion of the inclined wall 41which is below the opening 56,. the opposite side wall 40 and the frontand back walls 38 and 37 respectively. The cold air settling in thepocket of the ice chamber 36 will be further chilled and remain aroundthe ice, and prevent the circulating air from causing more rapid meltingthereof.

A drain 60 is connected with chamber 36 and extends through the lining29 and insulation 25 and into the compartment 21. This compartment isprovided with a'basin 61 for receiving water which water is conductedtherefrom by a drain 62. All water of condensation which takes placewithin the compartment 22 will flow into the chamber 36 whence it flowsto drain 60 into basin 61. Water from the melting ice within tray 50will also flow from the chamber 36 through the drain 60.

It is apparent from the foregoing description that a relatively simplerefrigerator has been provided. The partition wall between the coolingand food compartment provides means for readily draining water ofcondensation from the cooling compartment and also the melting ice. Thispartition wall also is formed in such a manner as to provide an icestorage chamber which may be maintained at a relatively low temperatureso that the ice blocks are not readily melted, and the construction andarrangement is such that a plurality of air passages are providedbetween the compartments located at different levels whereby naturalcirculation of air may take place between the compartments.
